Just like any hobby, fitness endeavor or game, practice leads to a higher skill level. Conscious creation is the same concept. When you practice daily and hone your powers, you heighten your ability to channel your own personal power.
And you can't save it up. If you don't practice your instrument for several weeks, you will notice that your play seems to come a little less naturally than when you practice every day. When you make daily practice of gratitude, mindfulness, and self love, you will find that those thoughts begin to come more naturally and easily.
The more your habit becomes ingrained, the more you will notice that little by little, day by day, everything is going more and more your way.
